According to arrest affidavits, Mondragon-Guzman would tell the mother of one of the victims that he was taking her son to the store. Instead, Mondragon-Guzman would take the boy to his Garland house, where he had sex with him.

The victim told police it happened "four or five times." He was also able to provide a detailed description of the inside of his coach's house and car, both locations where the alleged assaults took place.

Separate affidavits said the other victim told investigators that Mondragon-Guzman would promise to buy him things he needed for soccer and then abuse him. The documents also indicated that Mondragon-Guzman would show the boy pictures of naked people.
